Abstract

Estimating the potential zone of groundwater is an integral part of the coordination and planning of sustainable hydro-resources. The research exhibits a combined approach utilizing multi-criteria decision-making analysis (MCDMA) and geographic information system (GIS) techniques for the mapping of groundwater potential. GIS provides a platform for data integration, spatial analysis, and visualization of geospatial layers, whereas MCDMA allows the integration of multiple criteria to illustrate geomorphology, lithology, slope, rainfall, drainage density, land use, soil and groundwater depth, lineament, to evaluate and rank different alternatives. The combined approach offers several advantages. MCDMA allows for the consideration of multiple criteria simultaneously, capturing the complex relationships between various aspects influencing groundwater potential. GIS serves a spatial perspective, enabling the identification of areas for groundwater occurrence and facilitating efficiency. The Jonk River, a prominent tributary of the Mahanadi River basin, lacks studies addressing the hydrogeological characteristics, aquifer dynamics, and sustainable utilization found in this particular geographic area. The observations of the study reveal that about 8.38% of the area comes under a low groundwater potential zone, 85.1% of the area is considered a moderate condition of the groundwater prospective zone, and the remaining 6.5% of the area covers an excessive groundwater capacity region.

Research highlights

The study emphasizes the importance of integrating RS, GIS, and Multi-Criteria Decision Analysis (MCDA) techniques for groundwater management.

Created a groundwater potential map to ensure sustainable use and management.

The study employed MCDA with an Analytic Hierarchy Process to evaluate groundwater potential zones.

The research found that 85.1% of the study area has medium groundwater potential, 6.5% is classified as having high potential, and 8.38% has low potential due to the region's elevation.
